Third Party Certifications

As a manufacturer of building materials, Gardner® recognizes the importance of aligning our products with the many building codes and standards required by the market. Below is an explanation of some of the organizations that set standards for our industry. We've included the certification logos that each of our products qualify for on the individual product pages throughout our website.

	Over 12,000 ASTM standards operate globally. Defined and set by us, they improve the lives of millions every day. Combined with our innovative business services, ASTM standards enhance performance and help everyone have confidence in the things they buy and use – from the toy in a child’s hand to the aircraft overhead.
	As a global company with more than 120 years of expertise, UL works with customers and stakeholders to help them navigate market complexity. UL brings clarity and empowers trust to support the responsible design, production, marketing and purchase of the goods, solutions, and innovations of today and tomorrow.
	Choosing a product certified by NSF lets you know the company complies with strict standards and procedures imposed by NSF. From extensive product testing and material analyses to unannounced plant inspections, every aspect of a product's development is thoroughly evaluated before it can earn our certification.
	Miami-Dade Couty has some of the most stringent building codes in the United States due to the harsh tropical storms experienced in that part of the country.  You can search their database for products, certificates and listings that have been approved for use on buildings in both Miami-Dade County and throughout the country.
	The California Title 24 Building Energy Efficiency Standards are designed to ensure new and existing buildings achieve energy efficiency and preserve outdoor and indoor environmental quality. These measures (Title 24, Part 6) are listed in the California Code of Regulations. The California Energy Commission is responsible for adopting, implementing and updating building energy efficiency.
	The Cool Roof Rating Council was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance (radiative properties) of roofing products and to disseminate the information to all interested parties.
	Energy Star is a government-backed labeling program that helps people and organizations save money and reduce greenhouse gas emissions by identifying factories, office equipment, home appliances and electronics that have superior energy efficiency.
	The U.S. Green Building Council (USGBC) is committed to transforming the way our buildings are designed, constructed and operated through LEED — the top third-party verification system for sustainable structures around the world.  Every day USGBC is helping advance spaces that are better for the environment and healthier for us to live, work and play in.
